Application filed July 10, 1909.

To all whom it may concern:

Be it known that we, HENRY J. Harms and GEORGE E. SMALL, of Orange andWest Orange, respectively, in the county of Essex, and in the State ofNew Jersey, have invented a certain new and useful Improvement inMolding Apparatus for Houses, and do hereby declare that the followingis a full, clear, and exact description thereof.

Our invention relates to an improvement in molds, and especially to theconstruction of a set of molds adapted to be used in constructingconcrete houses. The set of molds which we have designed is adaptedparticularly to the construction of monolithic houses, that is to say,to houses which are made of a single block of concrete.

The object of our invention is to provide a set of molds of the abovecharacter, which will have the requisite strength and sustaining powerwhich may be readily erected and dismantle and which has manifoldconvcniences of different kinds, which will. be set forth in detailhereinafter in connection with the description of the particular partsthereof.

e have shown our invention in the accompanying drawings, in which-Figure 1 is a cross-sectional view of a portion of a house made with ourapparatus; Fig. 2 is a cross-sectional view in detail of the roofthereof; and Figs. 3 and 4 are respectively sectional and elevationalviews of two of the molding plates showing the mannor of connecting thesame together.

In the drawings we have shown an apparatus adapted to be used in themolding of houses by the pouring into the same of a body of concrete.The concrete may be preferably poured into the molds for the house allat one time, the same comprising a set of base plates 1, having widebottom flanges 2 and narrower upper flanges 3. Each of the plates 1 isstrengthened by a vertical and horizontal rib l. The plates are alsoprovided with side flanges 5, the side flanges 5 and the upper flanges 3being provided with bolt holes to permit the plates 1 to be securedtogether by means of bolts 7 The upper flanges of the plates 1 areprovided with recesses 8, as shown in Fig. 1, to receive a correspondingrib 9 attached to the lower flange of the next succeeding tier ofplates, or to receive a detachable rod 10 arranged to be received in therecess 8 and in the Specification of Letters Patent.

corresponding recess 11, as shown in Figs. 3 and l. The arrangement ofthe recess 8 and the projection 9, or the alternative arrangement of therecesses 8 and 11 and the rod 10 is provided so as to permit thesucceeding tiers of plates to be placed exactly in alinement, and alsoto permit the pivotal removal of the upper tiers of plates as the set ofmolds is being dismantled After the base plates 1 have been placed inposition, a next succeeding tier of plates 12 is applied thereto, theplates 12 being constructed in substantially the same manner as the baseplates 1, except that the upper and lower flanges thereof are exactlythe same in width. The plates 12 are bolted to the base plates 1 andadjacent plates of the same tier, by means of bolts, as described inconnection with the base'plates 1. Vertical and horizontal ribs are alsoprovided to strengthen these plates, in the manner described inconnection with the base plates 1. All of the remaining plates used inthe construction of the mold for the house, except those describedhereinafter in detail, are constructed exactly like the plates 12,except for variations in size at different points in the house.

In producing ornamental designs upon the exterior of the house, specialmolds 13 for this purpose are bolted to the interior of the outermolding plates. This method is used where the design comprises a hasrelief or extension inwardly from the primary position of the outermolds. If it should be desired, however, to produce an ornamental designby the opposite method, that is to say, extending beyond the normalposition of the molding plates, the mold can be set outwardly out ofalinement with the normal position of said plates, and then moldingplates 14 can be bolted to said latter outer plates to produce what maybe called an intaglio design, as shown in Fig. 2.

Instead of using molding plates for mold ing the exterior of the roof ofthe house, the roof 18, as shown in Fig. 2, may be first molded in slabsand then placed in position upon the top of the house to take the placeof the exterior molding plates at this point.

Inasmuch as the interior plates provide no point of advantage from whichthe first plates to be removed may be removed, it is desirable toprovide some special means to assist in the removal of the first plates.For this purpose we provide in the interior of the house key plates 24.The key plates 24 are constructed with one or more perpendicular flanges25 and one or more inclined flanges 26. The inclined flanges 26, ifdeusual to substitute for one of the square plates of the usual type anumber of key plates 24, located at right angles to each other, and acomplementary plate 27 to fill up the remainder of the opening left bythe square plate. Key plates 24 may also be substituted in the angles orat any other clesired point upon the interior or exterior of the house.

v In order to permit the molding of a smooth floor, each floor of thehouse is preferably provided with one or more risers 29 to allow theescape of air. v

7 At any point in the house where it is desired to attach woodwork,tapestry, or carets- We make rovision for insertin 7 2:)

wooden blocks 30 by means of thumb screws Copies of this patent may beobtained for 31, the thumb screws 31 being removed before the moldsattached thereto are removed.

In order to properly brace the exterior and interior sets of molds atvarious points throughout the house the molding plates are provided withperforated bosses 32 to receive bolts 33 passing from one set of moldingplates to the other. A bolt 33 is provided at one end with a slot 34having a pivoted cross-piece 35 supported upon pivots in said slot, ofthe same width as the thickness of the bolt, and having at its other enda hole to receive a pivot 37 of a cam 38 having attached thereto anoperating arm 39.

While we have described our invention above in detail, we wish it to beunderstood that many changes may be made in the details thereof withoutdeparting from the spirit thereof.

We claim y In a device of the character described, a mold adapted tomold plane surfaces, said mold being made of a plurality of plateshaving flanges, said flanges having a common pivotal means comprisingrecesses located between said flanges and a removable rod fitting insaid recesses.

In testimony that we claim the foregoing we have hereunto set our hands.
